About

Ayres Associates is proud of the innovative engineering and architectural solutions it has provided for more than 55 years. We deliver services in transportation, civil, structural, water resources, levee, and river engineering; architecture; landscape architecture, planning, energy corridors; environmental science; surveying; geospatial services; and GIS.

Our offices are in Wisconsin, Florida, Colorado, Wyoming, and Arizona.

Our firm is ranked 310th among the top 500 architectural/engineering firms in the nation by Engineering News-Record magazine. We first were ranked on the ENR list in 1972, and our revenues have kept us among this caliber of firms ever since.

Ayres Associates was founded in 1959 by Owen Ayres, a structural engineer who instituted many of the practices our company follows: working with clients as a partner; offering smart, creative solutions to clients' needs; conducting business with the utmost integrity; and providing employees not only a challenging work environment, but also the opportunity to advance and invest in their own company.

Those principles are core values of Ayres Associates. We are an employee-owned firm that provides innovative, progressive, and intelligent engineering services nationwide to clients we know by name.

Ayres Associates was coming up with pragmatic ways to save resources – and clients’ money – long before green became fashionable. Our engineers and scientists strive to minimize our clients' impact on the environment, and we have taken dozens of steps to reduce our own footprint.
